Simultaneous dual-frequency induction heating requires less energy and space than earlier dual-frequency induction heating systems and can be more easily incorporated into an automated manufacturing line or flexible work cell. The process provides a cost benefit by allowing the use of high-carbon steels rather than the more expensive alloy steels used with thermochemical treatments and powder metallurgy products. The reduced overall heating associated with the simultaneous dual-frequency induction heat treating technique improves the microstructure of the hardened area, has minimal effect on material core properties and, in most cases, eliminates the need for finish machining to meet dimensional specifications after hardening.
